(b El Oro, nr Acambaro, 7 March 1905; d Mexico City, 27 Oct 1924). Mexican painter and teacher of Scottish descent. He studied briefly at the Escuela Nacional de Bellas Artes, Mexico City, where in 1921 he met the painter Manuel Rodríguez Lozano, who introduced him to Mexican avant-garde artists. Under Rodríguez Lozano’s tutelage he joined the ‘brigade’ of teachers who trained primary and secondary school students using Adolfo Best Maugard’s method of teaching drawing based on the motifs of popular art. Angel developed a pictorial style characterized by a deliberately naive drawing technique and vivid, unnaturalistic colours; he typically made portraits of friends and relatives superimposed on backdrops of village scenes or simplified rural landscapes. A commemorative book published shortly after his death featured texts by major artistic and literary figures of the period, including Rodríguez Lozano, Diego Rivera, José Juan Tablada and Xavier Villaurrutia, and revealed the process of romantic mythification of Angel, characterizing him as a ‘pure popular painter’ and even inventing for him exotic Argentinian origins.
